[0025] The following specific embodiments illustrate the detailed implementation of this utility model. Those skilled in the art can easily understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in this utility model.

[0026] Example: An in-mold cutting and feeding device, such as Figures 1 to 4 As shown, it includes a fixed base 1 and a left cutting module 2 and a right cutting module 3 disposed on the fixed base. A through hole 11 is provided in the middle position of the fixed base, and a fixing rod 4 for placing the filter screen 10 can pass through the through hole and move along the through hole.

[0027] The left cutting module 2 includes a left cutting drive cylinder 21 and a left cutting block 22. The left end of the left cutting block is fixedly installed at the power output end of the left cutting drive cylinder. The right cutting module 3 includes a right cutting drive cylinder 31 and a right cutting block 32. The right end of the right cutting block is fixedly installed at the power output end of the right cutting drive cylinder.

[0028] The fixed base is provided with a guide groove 12, and the left cutting block and the right cutting block can slide along the groove;

[0029] The right side of the left cutting block and the left side of the right cutting block both form a semi-circular cavity 221. When the two semi-circular cavities are closed, they form a cavity for holding the fixing rod.

[0030] The in-mold cutting and feeding device also includes a material-grabbing claw 5 that can move at any angle in three-dimensional space, and the material-grabbing claw can grab the cut filter screen.

[0031] In this embodiment, the tail of the fixed rod is installed at the end of a feeding robot (not shown in the figure), and the feeding robot pushes the fixed rod to move horizontally. Other feeding mechanisms can also be used, as long as they can drive the fixed rod to move the filter screen horizontally for feeding. For example, a servo motor and lead screw structure can be used. The fixed rod is installed on a moving base, and then the moving base can be stably driven to move horizontally by the servo motor and lead screw structure described above.

[0032] In this embodiment, the material-grabbing gripper is a pneumatic gripper. The gripper arms include a left gripper arm 51 and a right gripper arm 52. The opposite sides of the left and right gripper arms form grooves that match the shape of the filter screen. The material-grabbing gripper is mounted on the end of a material-grabbing robot (not shown in the figure). The material-grabbing robot drives the gripper to grasp the cut filter screen and place it at the desired position in the mold.

[0033] In this embodiment, the cavity formed by the two semi-circular cavities has a tapered opening 222 on the side near the material-picking gripper. This structural design ensures that the filter screen is cut at the tapered opening, resulting in a good cutting effect and eliminating the problem of incomplete cutting.

[0034] In this embodiment, the filter screen is fitted onto the outer circumferential surface of the fixing rod.

[0035] In this embodiment, the fixing rod is a rigid metal rod. Because the filter screen is generally made of stainless steel mesh or fabric, the fixing rod will not be cut when the filter screen is cut, thus extending the service life of the fixing rod.

[0036] like Figure 5 As shown, Figure 5 The specific structure of the mold is not shown. The male mold of the mold used for injecting plastic shells is provided with two molding sliders 202 and a mold core 203. The space between the two molding sliders and the mold core is the molding cavity. The above structure is the basic structure of conventional molds, so it will not be described in detail. When the mold is split, the two molding sliders will separate, and the cut filter screen will be placed in place. Then, after the mold is closed, the two molding sliders will be driven to merge, and then the injection molding process is completed.

[0037] The working principle and process of this utility model are as follows:

[0038] The fixed rod is used to fix the filter screen feeding. The tail of the fixed rod can be installed at the end of the feeding robot. The feeding robot pushes the fixed rod to move and feed the filter screen. Alternatively, other feeding mechanisms can be used as long as they can drive the fixed rod to move and feed the filter screen.

[0039] A fixed base is used to guide and fix the cutting slider;

[0040] The left and right cutting drive cylinders are used to push the left and right cutting blocks to move and cut the filter screen together.

[0041] The material handling gripper is used to feed the cut filter screen into the forming cavity of the mold; specifically, the material handling gripper can be installed at the end of the material handling robot, and the material handling robot drives the material handling gripper to grab the cut filter screen and place it into the forming cavity of the mold.

[0042] The left and right cutting blocks are used to cut the filter screen.

[0043] A mold is used to fix plastic molding sliders (a part that forms a molding cavity between two molding sliders);

[0044] Molding sliders are used for plastic molding.

[0045] Workflow: The feeding robot pushes the fixed rod to move and feed the filter screen to the required length. The left and right cutting drive cylinders push the left and right cutting blocks to move and cut the filter screen together. The picking robot drives the picking claw to grab the cut filter screen and place it into the molding cavity of the mold to complete the injection molding.

[0046] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
